The Function of a Subordinating Conjunction

When a sentence has an independent clause (main clause) and at least one dependent clause, it is known as a complex sentence. In a complex sentence, the dependent clause establishes a time, a place, a reason, a condition, a concession, or a comparison for the main clause. (The subordinating conjunction provides the bridge between the main clause and the dependent clause.)

Real-Life Examples of Subordinating Conjunctions

• I find television very educating. Every time somebody turns on the set, I go into the other room and read a book. (Comedian Groucho Marx)
(The subordinate clause establishes a time for the main clause.)
• Wherever the art of medicine is loved, there is also a love of humanity. (Greek physician Hippocrates)
(The subordinate clause establishes a place for the main clause.)
• People are more violently opposed to fur than leather because it's safer to harass rich women than motorcycle gangs.
(The subordinate clause establishes a reason for the main clause.)
• Man is ready to die for an idea, provided that idea is not quite clear to him. (Author Paul Eldridge)
(The subordinate clause establishes a condition for the main clause.)
• I'm always ready to learn, although I do not always like being taught. (Sir Winston Churchill)
(The subordinate clause establishes a concession for the main clause.)
• Everyone else my age is an adult whereas I am merely in disguise. (Poet Margaret Atwood)
(The subordinate clause establishes a comparison for the main clause.)

With one dependent clause and one main clause, these are all complex sentences.Read more about the different types of sentences.

Some More Examples of Subordinating Conjunctions

Below are some more examples of subordinating conjunctions in sentences. Remember that the role of the subordinating conjunction and subordinate clause is to establish a time, a place, a reason, a condition, or a concession for the main clause. This means the clauses in bold are all functioning as adverbs. They're all adverbial clauses.
